  • 摘要: 基于两势方法系统地研究了质子数51 ≤ Z ≤ 83质子放射性核素的衰变半衰期。总的质子-子核相互作用势包括：通过单折叠子核密度和DDM3Y有效相互作用得到的微观核势，通过单折叠子核电荷密度和质子-质子库仑相互作用得到的真实库仑势以及离心势。同时，预测了同一区域16个核的质子放射性半衰期，并且预测的质子放射性半衰期在4.11倍的范围内。此外，还研究了质子放射性的Geiger-Nuttall定律。结果表明，Geiger-Nuttall定律可以用来描述角动量相同的同位素的质子放射性。


    In the present work, we systematically study the half-lives of proton radioactivity for 51 ≤ Z ≤ 83 nuclei within the two-potential approach. The total emitted proton-daughter nucleus interaction potential is composed of the microscopic nuclear potential obtained by single folding the density of the daughter nucleus with the DDM3Y effective interaction, the realistic Coulomb potential obtained by single folding the charge density of the daughter nucleus with the proton-proton Coulomb interaction and the centrifugal potential. We extend our study to predict proton radioactivity half-lives of 16 nuclei in the same region within a factor of 4.11. In addition, the Geiger-Nuttall law for proton radioactivity is researched. The results indicate that the Geiger-Nuttall law can be used to describe the proton radioactivity isotopes with same angular momentum.
